Service space: Outdoor unit
Outdoor unit:
• When mounting units side by side, the piping route must be to the front, to the back or downwards. In this case the piping route to the side is
not possible.
• When mounting the units side by side and routing the piping to the back, you must keep a distance of ≥250 mm between the units (instead of
≥100 mm as shown on the figures below).
